Full Breakdown
Huntsville's flood hazard district regulations (Zoning Ordinance Appendix A, Article 62) require new construction or substantial improvement of a residential structure in the floodway fringe (zones AE or AH) to have its lowest floor, including basement and garage, elevated at least one foot above the base flood elevation. Nonresidential structures must meet the same one-foot freeboard or be floodproofed to that level and certified by a registered engineer or architect. A floodplain development permit from the city engineer is required before any land-disturbing or building activity in the flood hazard district.
Violations & Fines
Working in the floodway or floodway fringe without a floodplain development permit is a misdemeanor; on conviction the offender is fined under Sec. 91.6 (general penalty).
